Support function to set background-image?

[Qard]

It might be neat to do something like have a function to define the background-image value, that way stuff like gradient overlays could be supported. It's easy enough to modify the rest of the css with !important flags in the css config value, but if you want to do something like background-image: linear-gradient(rgba(0, 0, 0, 0.2), rgba(0, 0, 0, 0.4)), url(randomImage); rather than using the opacity property, you can't really do that currently.

Sorry for the super late response here!

That's a good idea, I'll see what I can put together soon, but I'm also not opposed to people putting together their own PR's if you would like to give it a shot.
